Abstract

Un proceso para la producción de alquil éteres incluye alimentar una materia prima de hidrocarburos y una primera materia prima de alcohol a un reactor de lecho fijo que contiene un catalizador de eterificación. La materia prima de hidrocarburos y la primera materia prima de alcohol entran en contacto en el primer reactor de lecho fijo para hacer reaccionar las isoolefinas con el alcohol en presencia del catalizador de la eterificación para producir un primer flujo de producto. El primer flujo de producto se alimenta junto con una materia prima de hidrógeno y una segunda materia prima de alcohol a un sistema de reacción de destilación catalítica que contiene un catalizador trifuncional para isomerizar concurrentemente al menos una parte de las alfa-olefinas e hidrogenar al menos una parte de las diolefinas y eterificar al menos una parte de las isoolefinas y alcohol, produciendo productos residuales que comprenden uno o más éteres y un producto suspendido que comprende n-alcanos, isoalcanos, alfa olefinas sin reaccionar, olefinas internas sin reaccionar y alcohol sin reaccionar.A process for producing alkyl ethers includes feeding a hydrocarbon feedstock and a first alcohol feedstock to a fixed bed reactor containing an etherification catalyst. The hydrocarbon feedstock and the first alcohol feedstock are contacted in the first fixed bed reactor to react isoolefins with the alcohol in the presence of the etherification catalyst to produce a first product stream. The first product stream is fed together with a hydrogen feedstock and a second alcohol feedstock to a catalytic distillation reaction system containing a trifunctional catalyst to concurrently isomerize at least a portion of the alpha-olefins and hydrogenate at least a portion of the diolefins and etherify at least a portion of the isoolefins and alcohol, producing residual products comprising one or more ethers and a slurry comprising n-alkanes, isoalkanes, unreacted alpha olefins, unreacted internal olefins, and unreacted alcohol.
